LABEL- SPECIFICATION forming part of Letters CUTTER.

Patent No. 272,202, dated February 13, 1883.

Application filed May 2, 1882. (No model.)

To all whom it may concern Be it known that I, MILTON BRADLEY, a citizenof the United States, residing at Springfield, in the county of Hampdenand State of Massachusetts, have invented new and useful Improvements inLabel-Gutters, of which the following is a specification.

This invention relates to improvements in label-cutters,vand hasrelation more particularly to the construction in this class ofpapercutters of an improved binder to press upon the paper near theknife, of an automatic gage, and of devices for holding and moving thepaper, the object being to provide improved devices for attaching apaper-binder to a machine of this class, which is adapted to moveparallel with the knife and bed and to adjust itself, so as to bear withproper force upon the paper near the knife and quite across its sur-'face; to provide a gage which is automatically moved to and from aproper position behind the knife, and a label-clamp to retain a seriesof paper-sheets of small dimension in a level position upon the bed ofthe machine.

In the drawings forming part of this specification, Figure -I is an endelevation, partly in section, of a label-cutter embodying my invention.Fig. II is a side elevation, partly in section, of said machine. Fig.III is a side elevation of the label-clamp and a section of the bed ofthe machine. Fig. IV is a section of the gage-shaft and itsdirectly-connected rotating connections. Fig. V is a plan view of thecentral portion of the bed and thelabelclamp thereon.

The operating parts of this machine aresupported upon the frame A,ofcast-iron, to which are bolted or otherwise suitably secured the legs B.The said frame has cast upon each side thereof the verticalknife-frame-supports 0, each having a corresponding vertical slot,within which the knife-frame d is fitted and adapted to slide.

The bed D is made preferably of hard wood, and is provided with a seriesof'longitu'dinal grooves, 0 in which the back gage and the label-clampare guided in their movements toward the knife. Said bed is secured onframe A by suitable screws and rests .upon transverse blocks 42.

The knife-frame d has its opposite faces properly finished, and hasparallel vertical bearings therefor.

Aseries of adjusting or gib screws, 2 2 2, is placed in said supports 00, each side of the slots therein. The knife-frame is fixed in a propervertical position between the edges of said slots, and a suitable.gib-strip is placed on each side of said frame, and the screws 2 beingturned against the rear face of said knife-frame on opposite sidesthereof, and said frame is thereby held in a proper vertical po sitionin said supports 0.

The ends of the knife-frame d extend outwardly beyond the sides of thesupports 0 c, and, have attached thereto by suit-able pivotbolts theends of the connecting-rods a Two shalt'supports, h h, are provided onthe under side of the fra'meA,in which are formed suitableboxes,in whichto hang the transverse rock-shaft a. In each end of said shaft, whichextends outwardly beyond the sides of said frame, is placed a pivot'boltin a position to rotate eccentrically to the axis of said shaft a, andwhereby the two connecting-rods c a are connected with said shaft. i

A lever-handle,f, is secured on one end of shaft to, by which the latteris rocked, and whereby the knife-frame is given a reciprocatin gvertical motion.

Au arm, a", is provided on shaft a, to which is pivoted oneend of aspring supporting-rod, c and the opposite end of the latter passesthrough the end of frame A under the bed D.

A spring, 50, is placed on rod 0 between a shoulder on said rod, neararm of, and frame A. When shaft on is rocked to operate the knifeswingsup a little above the axial line of shaft or, when the force of saidspring acts to assist the rotating movement of said shaft, and thislast-named action of spring occurs at the time when the resistance tothe descent of the knife through the pile of paper is the greatest, andthus aids rather than otherwise in carrying the knife down, and when thehandle-lever fis swung back to lift the knife-frame, bringin g the partsto the positions shown in Fig.2, said spring 50 operates to hold theknife-frame and said handle in those positions.

A self-adj usting paper-binder, e, is hung on strips, the latter areheld firmly against theframe, spring 50 is compressed until arm a ICOjections on said frame, as shown.

the front face of the knife-frame d to two vertical posts, 6 which aresupported and guided so that they,with sa d binder, may have a freevertical movement in suitable perforated pro- The said posts 0 areconnected to the slotted arms of two evener-levers. 8 8, which arepivoted on the face of said knife-tratne, and are provided each with anupright arm, to or between the upper ends of which is connected aspring. 9. Said evener-levers are pivoted together at the point 15 oftheir intersection by a pin fixed in one. of them, which passes throughan oblong slot in the other one, and screws or pins fixed in posts apass through longitudinal slots in the said evener-arins, as shown inFig. 1.

Stop-pins are fixed in posts 6 to arrest the latter at a proper point intheir downward movement, or to let the under side of the binder e, whenat rest, stand about on a line with the edge of the knife (I.

The action of spring 9 and the evener-levers upon the binder e is tocause the latter, as the knife-frame and knife move down, (the latteragainst a pile of paper to cut it,) to press steadily and firmly uponsaid paper close by the edge of the knife, and to prevent any of thesheets composing said pile of paper from being drawn by the action oftheknife, whereby imperlect work would be done.

It \\'Ill be seen that said binderc and its above-described connectionsmove down with the knife-frame until said binder strikes the pile ofpaper 00, placed under the knifed to be cut, when the motion of thebinder is arrested, except so far as it may be forced by the action ofspring 9, and the frame d and knife dcontinue to move down until thelatter shall have passed quite through said paper, the lower edge ofthat part of frame (1 beyond supportsc c then striking the ends of thestop-screws 7 7 and stopping the motion of said frame. The binderecontinues to hold the paper firmly in place until the knife (I shall belifted quite away from it.

The evener-levers S, as constructed and applied to the knife-frame andconnected to the posts e compel the binder c to move down, with itsunder side always parallel to the face of the bed 1) anti with the edgeof the knife, whether the thing to be out be placed centrally betweenthe ends of said hinder or not.

The rear edge of the bindere is beveled off, as shown in Fig. 2, toafiord facilities for looking down between said binder and the adjoiningface of the knife, so that the paper can be accurately adjusted to apropercntting-line, if need be, otherwise than by depending solely upona gage.

A gage, 71, adapted to restin the rear of the knife d and form a stopagainst which the end of a pile of labels or of paper may be placed todetermine their width when out, is supported adjustably on agage-rod, 2'so thatit maybe moved toward and from said knife.

The downhanging end of said gage n is slightly below the surface of bedD, and has an oscillating movement in a groove, 0 back of knife d. Thusthe lower sheet of a pile of paper, as well as those above it, strikessaid gage when adjusted beneath the knife. Said gage-rod i is adjnstablysecured in the end of the gage-arm i by a thumb-nut,o, and aspring, 12the latter operating between a pin in said rod and said arm. Saidgage-arm is secured on 'a transverse rock-shaft, m. (see Fig. 1,) whichis hung on the rear side ofthe supports 0 c and back of the kni e-frame.and a short horizontal arm, '1 on said gage-arm strikes the rear side ofthe knife-fra me when arm i is in the position shown in Fig. 1, andthere causes it to he held.

A short rack, c, is fixed on one end offramc d, and a pinion. a, hung onthe end of shaft m, engages with the teeth of said rack. Said pinion iis adapted to have a limited free motion on shaft m, as follows: Pinioni is provided with a hollow hub, tKFig. 4, havingone of its sides cutaway for about half of its length.

A pin, t. is fixed in shaft to in such position that one lip of the hubit will strike it wh n pinion iis turned in such a direction as willoperate shaft at, so as to swing arm 2' in the direction indicated bythe arrow in Fig. 2, and a coiled spring, 2, is placed on shaftm, oneend of which engages with a pin in said shaft, and its opposite endengages with the lip of hub t opposite the one which,as above described,strikcs pin t.

The above-described construction of the pinion 11 and its connectionwith shaft m by the said pins and spring 2 are for the purpose ofallowing a certain movement to frame at without turning shaft m, andwhereby, when the knife-frame is approaching its highest point and theend of arm you arm 1' is restingagainst said frame, pinion imay rotateslightly against the tension of spring 2 and cause the gage a to beheldfirmlyin position bytheforce of said spring; and, furthermore, said cornstruction provides for allowing the frame d and knife 01 to descend andthe latter to begin to out the paper before pinion t has rotated againstpin t and commenced to turn shaft m and to lift up arm 71 and swing gage12. away front the knife and the end of the pile w of paper, thusholding the latter in position until the binder e and the knife havecontrol thereof. Said gage is adjustable on rod i for generaldimensions; but when it is desired to adjust the gage so that cuttingmay be done very accurately said gage is adjusted finally by the aid ofthe screw 0 and the spring id.

The clamp H is especially constructed for use with this machine, andconsists of an upperandlower plate, hinged together, asshown, one end ofthe upper one being provided with a thumb-screw, whereby the oppositeends of said plates are caused to approach each other and clamp a seriesof sheets of paper and hold them while being out. On the .lower one ofwork which does not elevate oneend of the pile, as is usual, above theface of the bed, thus keeping the paper in the best position to insurethe best work. In using said clamp the paper a is secured in it,and,placing the block 5 in one of said grooves in bed D, the paper ispushed along under knife (I and against the gage a.

A back gage, n is provided for pushing for ward paper, having likewiseguide-blocks w thereunder to follow in 'saidgrooves e in bed I D, andthus compel its edge next to the paper 00 (see Fig. II) to standparallel with the knife, and consequently serve to forward thepaper-pile to a true position under the latter, so that it may beproperly out.
